Donald Trump Jr., the president’s oldest son and executive director of the Trump Organization, will meet with the Senate Judiciary Committee on Thursday to discuss a June 2016 meeting he set up with a Kremlin-backed lawyer and other Russians promising compromising information on Hillary Clinton. Trump’s testimony, originally scheduled for July, will be transcribed but held behind closed doors. The Senate Judiciary Committee, headed by Sen. Charles Grassley (R-Iowa), is one of three congressional panels looking at Russian interference in the 2016 election, but Grassley’s committee is focused more on potential obstruction of justice and issues surrounding foreign lobbying than possible collusion with Russia. Trump will be the first insider from his father’s presidential campaign to appear before the committee.
